Frequently Asked Questions


Will the Manual Air Recovery System work on my Classic Range Rover? (1993-1995)
M.A.R.S. will absolutely work on a Classic Range Rover. The Multi-Mode M.AR.S. is currently the only system we have available for the Classics. The major difference being the valve block is located under the frame rail on the Classic, as opposed to, under the hood on the 4.0/4.6. You will also have to find a place to locate the bracket on the classic because there is no place to mount it on the core support like the 4.0/4.6. The bracket is simple enough to mount just about anywhere. We supply 50 feet of air line so you will have enough to mount it anywhere. There is no difference in the operation or function of MARS. It is basically a different installation procedure.


What is the difference between the Multi-Mode M.A.R.S. and the Single-Mode M.A.R.S.?
The main difference between the Multi -Mode MARS and the Single-Mode MARS is convenience. The Mult-Mode MARS uses a T connection to connect the manual fill valves. This setup uses the existing check valves in the valve block to hold air. MARS is installed once and can remain connected even when the EAS is working. This is by far our best selling system because it is there the next time your EAS faults.

The Single-Mode MARS is connected directly to the air spring lines. You must disconnect each air line from the valve block and plug it into the manual fill valves. You must do this each time you wish to manually fill an air spring. When the EAS fault is corrected, you must disconnect MARS and reconnect the air springs to the valve block.


Do you ship internationally?
Shipment outside of the United States is never a problem. We know the Land Rover “quirks” are not limited to NAS vehicles. All of our international shipping is done via the United States Postal Service (USPS) because of their low postage and reliable service, but we are more than happy to ship with anyone upon request. We offer the USPS Airmail and Global Express Mail services. Airmail service ($22) is usually delivered within 3 weeks and DOES NOT offer internet tracking. The Global Express Mail ($44) has a 5-7 business day delivery and can be tracked online. We always recommend the Global Express Mail because you can track it online and delivery is much faster.

How can you install MARS with only a screwdriver?
The supplied air hose fittings in M.A.R.S. do not require special tools to install. Connections are made by pushing the air line into the connector until it stops. Once the air line has been pushed into place, it is automatically locked in place by small teeth. To release a hose from a connector you must push the collar of the connector in and hold it while you pull the hose out. DO NOT PRY THE COLLAR. Connecting and disconnecting the air line does not require a lot of force. The same procedure applies to the connectors on the valve block.
